Plex fails to restart after update
Not sure if this helps anyone else but thought I'd share
Root cause: Plex 1.43.2 introduced code that initializes NVIDIA CUDA at startup, but it immediately segfaults in libcuda.so.580.142 — a compatibility bug between this Plex version and your NVIDIA driver.
Fix: Created /etc/systemd/system/plexmediaserver.service.d/disable-cuda.conf which sets CUDA_VISIBLE_DEVICES= (empty), preventing Plex from accessing any CUDA/GPU device on startup.
Side effect: Hardware-accelerated transcoding via CUDA (NVENC) will be disabled. You can still use Intel Quick Sync (i915) for hardware transcoding since you have that too — configure it in Plex Settings → Transcoder → Hardware Transcoding.
If you update your NVIDIA driver in the future and the crash goes away, remove the override with sudo rm /etc/systemd/system/plexmediaserver.service.d/disable-cuda.conf && sudo systemctl daemon-reload.
